Constant noise around 2 kHz
"?ish" wrote in message oups.com... Hello all, Why does SW radio comes up with noise the moment I dial beyond AM. I have tried tuning with several radios (including Sony 2010) and for some reason noise level seems to increase around that band. I tried with both AC adapter and plain old battery. Any ideas? Many multiband radios (at least the better than bottom quality ones) use higher gain stages above the AMBCB. This can either be an extra stage of RF amplification, or a separate one, or an attenuator for frequencies below 1.7 MHz. More gain usually equals more noise (from outside sources). |
